Serial No. 166,382.

This invent-ion relates to stove construction, and has for its obj ect an improved enamelling stove structure, providing what is be'- lieved to be a novel idea in making the enamel parts, most liable to damage, easily replaceable.

, Glass enamelled stoves have come into vogue and cooking stoves are now made which have practically all the surfaces thereof enainelled. Attempts have been made to enamel the entire oven front frame, but such attemptshave not 'been successfulvfor the reason that the space between the broiler andv oven has quickly become stained and cracked, and very unsightly. In order to overcome such defects it has heretofore been necessary to replace the entire oven front frame, which isa very expensive proposition,

due both to the cost of material and time of 2o replacement. -My present invention is. di-

rected to provision ofthe one-piece oven front frame, the entire surface of which may be enamelled, and which is provided with small, removable parts at those points most susceptible to damage.

In the drawings: y. Fig. lis a fragmentary prespective show-y ing the removable facing strip below `the oven opening.

Fig. 2 is a perspective of'this strip.

Fig. 3 is a. section taken on the line 3-''3 of Fig. 1.

Fig. 4 is a rea-r elevation of the'structure between the oven and the broiler chamber on the inside.

Fig. 5 is a section on the line 5--5 of Fig. 4. Fig. 6 is a section on the line 6--6 of Fig. 4. Fig. 7 is a fragmentary enlarged perspective, showing how the facing strip and the 4o oven come together.

a designates the stove structure whichV forms the upper oven and the lower broiling chamber in' accordance with common practice. A ldoor b acts' as a closure for the oven,

and a door c for the broiling chamber. The front frame d is usual-ly either a casting or a pressed metal member which is ordinarily not glass enamelled even in those stoves which A affect to be enamelled. 'The reason for this :so is that this frame is exposed to considerable heat, and also the drippings of things boiling over on the oven flowing out on the frame. It has, therefore, been found that the glass enamelling of this frame is not attended with successful service as the enamel coating becomes crazed, fractured and 4stained, especially immediately under the oven where the heat is considerable, and y where cooking materials boil over on the same, and often stain and crack; This is especially true where this enamely becomes eX- tremely hot and cold when things are spilled over it. This willcause the enamel to craze and fracture.

Due to these causes some of the stove builders have found it advisable to use a plain metal front frame or a nickel frame. However, I have discovered that the difliculty may be largely remedied by constructingvthe front frame so as to laHord an easily replaceable enamelled oven threshold facing strip. That is, when in the course of usage the enamel becomes checked, or broken or stained, another strip'may be easily installed at a very small cost. This enables the entire front ofthe stove-to be enamelled` in accordance with the general plan, and adds very much to the clean,

vneat appearance of the stove- To accomplish. this purpose. Vwe use a pressed metal front frame d which is glass enamelled all over, preferably with three coats, to wit: the usual blue ground coat and two finishing coatsl of white enamel. The entire frame front and back is provided with the blue coat which is applied by dipping. Only the front of the `frame is provided withthe White coats which are sprayed on, Preferably the center bar e has the regular blue ground coat of enamel, and then the'face of heat to the front of the center bar-so that it `wi1l not craze the enamel of the center bar.

This heat insulating strip is, therefore, also useful in protecting the enamel on the center bar itself as well as the enamel on the removable facing strip of the thresholdt It will V be apparent that the same idea can be carried out in connection withthe other parts of the stove that are subjected to the same enamel .deteriorating conditions.

The'center bar e has the `portion 1 which is offset from the front-frame l owing to the pressed-in portion 2. The ends of the facing .strip f form flush joints withthe front fralne d as at 3 as shown in Figs. 1, 3, and 7 The depression 4 above, and the depression 5 below, the facing strip f, as shown in Figs. 5, 6, and 7 form seats for the oven doors;

What I claim is:

l. In a stove, a glass enamel frontframe having a center bar with-an offset portion dividing the oven and broiler chamber, a removable threshold facing strip arranged to v fit nicely in said offset portion ush with the end portions of said center bar so that the facing strip and the end portions of the center bar are inthe same plane.

2.- In a stove, a glass enamel front frame having a center bar with an offset portion dividing the oven and broiler chamber, va removable threshold facing strip having longitudinal ianges arranged to fit nicely in said offset portion flush with the end portions of said center bar to permit an air space between the center bar and the removable facing strip.

3. In a stove, a front frame having a cen-- ter bar with an offset portion dividing the oven and broiler chamber, a removable threshold facing strip arranged to fit nicely in'said offset portion Hush with the end portions of said center bar, and studs on the inside of said facing strip for clamping said facing strip to said offset portion of the center bar whereby a smooth exterior face on the facing strip is permitted.

In testimony whereof I vhave affixed my signature.
